Answer:
A. The rice genes didn't make the right type of vitamin A.
Explanation:
Regular white rice does not have the gene to produce beta carotene. The human body converts the beta carotene into vitamin A.
To increase the nutritional value of rice, the gene for beta carotene from daffodil flowers was inserted into the cells of endosperm of rice.
This allowed these cells of the genetically engineered rice varieties to produce beta carotene. Production of beta carotene imparted golden color to the rice grain and hence, the name.
